Macro to change text in text fields

Hello community,

I create a weather map which I need to update pretty often. When updated I export it as PNG for Premiere Pro. There are 13 standalone text fields for temperature. Every time I update the weather forecast I need to go through all the fields and change temperature values.

The question is, what would be the best way to change these values automatically?

I would prefer using some kind of VBA form where I would quickly insert the values. It would be perfect to load the values from TXT file. I am new to creating macros in VBA.

I would  like to ask you for the right direction, I haven't found any tutorials regarding this kind of problem, the Print Merge function doesn't seem to be perfect for me.

Thank  you guys for your input, have a great day

Janek
